A longheld belief has been recently shaken
Could archeologists have been mistaken?
Despite the old tools once dug up in Clovis,
America's peopling in serious doubt now is..
It was long assumed that Asians crossed Bering,
In pursuit of seals, or perhaps it was herring...
But now from Brazil comes a brandnew assay,
Supported by comparisons of DNA,
That tools and some charcoal from Capivara
Tell an entirely different story:
They move back migrations by 10,000 years,
And related them to Africans, so it appears...
So, as each side their theory fiercely exhorts,
Were we invaded from South or from North?
Indeed why not both? Why fuss and why boast,
Instead of both sides drinking to Science a toast?...
